Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

PC On Demand - Distributed Personal Computer System

Abstract

The "Distributed Personal Computer System" (DPCS) describes a computer system. It provides a new way of computer components interaction. This could change the use of a PC (Personal Computer) in future dramatically.

At least one non-text object (such as an image or picture) has been suppressed.

This is the abbreviated version, containing approximately
40% of the total text.

The basic idea of the DPCS is the "decoupled arrangement" of the computer
components. This results in a huge flexibility and the possibility of providing
"performance power on demand" as hardware service.

The client component (hard disk, USB memory stick, etc.) is normally very
small (much smaller than a laptop) and stores all data (operating system and
application data). Therefore this component is very flexible and mobile. It can
be connected to a specified server component "on demand".
- Dynamic performance power "on demand":

The server component can be specified dynamically and provides the needed
performance power on demand.

Only when both components are connected, a working computer system is
created on demand. Several "service providers" can provide server components for
the "on demand use".

It is possible to access the own computer environment consisting of operating
system and application data anytime, anywhere. In addition to this the performance
power can be selected dynamically.

General

The "Distributed Personal Computer System" (DPCS) describes an
elementary change of the computer system. It requires a rethinking of the use of
personal computer systems. It does not assume that the components of a computer
system are fix connected representing one undividable unit. DPCS provides a very
flexible computer architecture with unforeseen possibilities and chances for the
future.

The aim of the idea is to make the fix connected components dynamic . It
does not mean the possibility to connect components dynamically inside one
computer system only to create virtual machines.

Status quo

Today the personal computer (PC) represents a fixed unit. It consists of
mainboard, CPU, display adapter, hard disk, etc. When changing one component of
the system, often a major modification of the operating system and driver software is
required.

It is not easy to use the "whole" software environment as "mobile" part
independent of the hardware components . Therefore it is hard to access the own
computer environment consisting of operating system and application data anytime ,
anywhere independent of the provided hardware.

For mobile use a laptop is often used. With this solution the entire computer
becomes mobile. But it still consists of one fixed unit, although all necessary data
